2014-08-12Minor Two pass rate control adjustments.Paul Wilkins
Alter way in which we identify static scenes. Remove some redundant code. Change-Id: I883c2ea2e341770648a8663d8881f720ed099b61
2014-08-08Moving framerate from VP9EncoderConfig to VP9_COMP.Dmitry Kovalev
Framerate changes over time, VP9EncoderConfig supposed to have static read-only data. Change-Id: I36580a7ee71243c1eabb57691089691731d03e67
2014-08-08Moving pass from VP9_COMP to VP9EncoderConfig.Dmitry Kovalev
We had a very complicated way to initialize cpi->pass from cfg->g_pass: switch (cfg->g_pass) { case VPX_RC_ONE_PASS: oxcf->mode = ONE_PASS_GOOD; break; case VPX_RC_FIRST_PASS: oxcf->mode = TWO_PASS_FIRST; break; case VPX_RC_LAST_PASS: oxcf->mode = TWO_PASS_SECOND_BEST; break; } cpi->pass = get_pass(oxcf->mode). Now pass is moved to VP9EncoderConfig and initialization is simple: switch (cfg->g_pass) { case VPX_RC_ONE_PASS: oxcf->pass = 0; break; case VPX_RC_FIRST_PASS: oxcf->pass = 1; break; case VPX_RC_LAST_PASS: oxcf->pass = 2; break; } Change-Id: I8f582203a4575f5e39b071598484a8ad2b72e0d9

2014-07-14[spatial svc]Implement alt reference framesMinghai Shang
All changes are for spatial svc only. 1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer 2. Use golden reference idx for spatial reference 3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers 4. Add "auto-alt-refs" in svc options Change-Id: Idf27d1fd2fb5f3ffd9e86d2119235e3dad36c178

2014-06-24Dual ARF changes: Buffer index selection.Paul Wilkins
Add indirection to the section of buffer indices. This is to help simplify things in the future if we have other codec features that switch indices. Limit the max GF interval for static sections to fit the gf_group structures. Change-Id: I38310daaf23fd906004c0e8ee3e99e15570f84cb

2014-06-24Clean out old CONFIG_MULTIPLE_ARF code.Paul Wilkins
Remove the old experimental multi arf code that was under the flag CONFIG_MULTIPLE_ARF. Change-Id: Ib24865abc11691d6ac8cb0434ada1da674368a61
2014-06-24Experiment for mid group second arf.Paul Wilkins
This patch implements a mechanism for inserting a second arf at the mid position of arf groups. It is currently disabled by default using the flag multi_arf_enabled. Results are currently down somewhat in initial testing if multi-arf is enabled. Most of the loss is attributable to the fact that code to preserve the previous golden frame (in the arf buffer) in cases where we are coding an overlay frame, is currently disabled in the multi-arf case.

2014-05-22Adjust cq_level in constrained quality modeDeb Mukherjee
If we are already saving a lot in bits from the target (maximum) bitrate in the constrained quality mode, allow the quantizer to go lower than the cq level. This hopefully will solve issues with getting too low a bitrate and consequently poor quality for certain videos in cq mode. Change-Id: I1c4e8b0171fcf58f95198b3add85eea5f3c8f19f

2014-05-13Tune minq index table for P frames in one_pass_cbr coding modeJingning Han

2014-05-07Remove separate arf and gf minq tables.Paul Wilkins
Merged minq tables for arf and gf cases. These tables were almost the same and for VBR the arf table was not used at all. Change-Id: Ie3c87e91dab613cf06f6945ac1ace0e0e4213d34
2014-05-07Rate control adjustment.Paul Wilkins
Small adjustment to the active Q range calculations. These changes should slightly extend the available Q range for KF/GF/ARF and narrow it for other frames. The results for this change in isolation are broadly positive for SSIM and average PSNR and slightly up but mixed for opsnr. derf +0.293% opsnr, +1.286% SSIM std-hd + 0.528% opsnr, + 1.746% SSIM yt +0.056% opsnr, +0.457% SSIM yt-hd -0.147% opsnr, + 0.226% SSIM Change-Id: If065280342027ecc5d44b49fc1d440dfef041002

2014-04-16Add experimental VBR adaptation method.Paul Wilkins
Add code to monitor over and under spend and apply limited correction to the data rate of subsequent frames. To prevent the problem of starvation or overspend on individual frames (especially near the end of a clip) the maximum adjustment on a single frame is limited to a % of its un-modified allocation.

2014-04-16Fix rate control bug.Paul Wilkins
Fix rate control bug whereby the rate factor heuristics were being updated on arf overlays causing a rate surge for a few frames followed by a corrective drop. This fix eliminates many of the overshoot problems that we were seeing on hard clips (even without applying stricter vbr rate control) and also helps quality on almost all clips with some hard clips improving by >5%. Overall quality results measured at speed 2. Derf +1.78% opsnr , +2.44% SSIM Stdhd +2.41% opsnr, +2.85% SSIM Change-Id: I2369df6295c2705963fa6307877f6acb304bcc39
